Offer to send her to work/school. So you can pick her up after that.
Borrow/Rent her favourite car for one day. You can do that at car rental shops.
I think all girls love BMWs.
Fetch her after work/school to a shopping complex. Pavilion?
Take her shopping!
Pay for her a new dress and shoes and earrings. for a classy dinner.
The dinner. I suggest Cafe Cafe KL or LeBouchon KL.
Both has romantic settings, good Italian/French food.
You should eat at home first,=) as the food there is served small and expensive.
Order the house Wine, and enjoy the night.
Make dinner reservations a week earlier, make sure u know where the restaurant is in advance, and
tell the waiter it's her birthday. they'll prepare a cake (complimentary). =) even better if you could
order in advance. she'll know you've been there earlier to be prepared.
and of course send her home and return the BMW.

Be the nicest gentlemen ever, and she'd want to marry you!
the aim of the night is to make her feel really special.

happy saving! coz a night like that will cause u a bomb.

No drama ler bro. Can be done.
That was exactly what i did.
